Therefore, since the insulated wire winding bind does not move within the variable guide portion, the winding operation of the insulated wire winding bind is facilitated and the working efficiency is improved as compared with the conventional guide portion that is not deformed.

  The method for attaching the winding binding for an annular insulated wire of the fourth invention to an electric wire is a loop for winding the winding binding for an annular insulated wire having an end formed in an annular shape around the electric wire in the direction of winding or removing. And an annular insulated wire using a winding grip tongue comprising a variable guide portion made of an elastic body and a raised portion for separating an end portion of the winding binding for the annular insulated wire from the wire. The winding guide is inserted into the inside of the variable guide portion, and the variable guide portion is moved in the winding direction in a state where the winding binding for the annular insulated wire is loosely gripped, and is formed in the annular shape. The portion excluding the end portion is spirally wound around the electric wire, and the winding binding for the annular insulated wire is attached to the electric wire so that the annularly formed end portion is separated from the electric wire. I am characterized in.

  According to the method of attaching the winding binding for the annular insulated wire to the electric wire according to the present invention, the winding for the annular insulated wire is wound in the state where the annular binding wire winding bind is loosely sandwiched by the variable guide portion. The binding is not movable within the guide portion and can be easily wound around the electric wire. Moreover, since the annular end portion is separated from the electric wire when the winding bind for the annular insulated electric wire is attached to the electric wire, it does not bite into the electric wire. Therefore, even if the winding binding for the electric wire and the annular insulated wire is repeatedly subjected to vibration by wind or the like, the electric wire is not damaged.

  The method for removing the winding binding for an annular insulated wire of the fifth invention from an electric wire is for winding the winding binding for an annular insulated wire having an end formed in an annular shape in the winding direction or the detaching direction with respect to the electric wire. Using a winding grip tongue comprising a loop-shaped variable guide portion made of an elastic body and a raising portion for separating an end portion of the winding binding for the annular insulated wire from the wire, The end of the annular insulated wire winding bind is separated from the electric wire by hooking the raised portion on the formed end, and the annular insulated wire winding bind is inserted inward of the variable guide portion, In the state of loosely grasping the winding binding for the annular insulated wire, the variable guide portion is moved in the removing direction, and the winding binding for the annular insulated wire is removed from the wire. And butterflies.

  According to the method of removing the winding binding for the annular insulated wire from the electric wire according to the present invention, the vicinity of the end of the winding binding for the annular insulated wire without damaging the wire by hooking the raised portion of the winding grip tongue on the annular portion. Can be separated from the electric wire.

  In addition, by loosely sandwiching the winding binding for the annular insulated wire with the variable guide part, the winding binding for the annular insulated wire is not movable within the guide part. It can be removed.

  According to the winding bind for an annular insulated wire according to the present invention, since the end portion is formed in an annular shape, it does not bite into the wire. Moreover, since an edge part does not bite into an electric wire, it becomes possible to remove the winding binding for annular insulated wires from an electric wire, without damaging an electric wire. In addition, by using the winding grip tong according to the present invention, it is possible to efficiently attach and detach the winding binding for the annular insulated wire in a short time.
